Patent GB-2119135-A (GB)
Title: Outlet metering load-sensing circuit
Inventor: JACKSON ALAN DAVID
IPC: F15B11/05
Filed: 1983-04-21
Abstract: A meter-out load sensing hydraulic system controlling one or more motors, supplied by a variable displacement pump (12) through a directional control valve (16). The pump control means (22) senses pressure and flow on the discharge or return side of the motor (14) to determine the pump cam plate (18) position. The signal line (30) connecting this discharge side of the motor (14) to the control means (22) is also supplied with a low pressure signal flow eg. via throttle (32) which causes the pump (12) to standby at a low pressure level in a neutral valve position or when metering down a gravity load. A check valve (34) prevents flow of return fluid from the motor to the pump control means. The load may be a rotory motor (86, Figure 4, not shown) eg for driving a fan or generator. <IMAGE>

IPC: F24B1/02
Filed: 1984-05-22
Abstract: A solid fuel-burning appliance comprises a housing containing a primary combustion chamber in which solid fuel is burnt in a fuel bed in the presence of primary air and a separate secondary combustion area which receives combustion gases from the primary combustion chamber and burns them further in the presence of secondary air before the residual gases pass out of the appliance through a flue. The secondary combustion area is constructed and arranged so that visual effects of the high temperature resulting from the burning occurring in that area are visible from outside the housing. Preferably artificial shapes of refractory material are in or above the second combustion area to give an artificial fire effect on being heated. <IMAGE>

Patent GB-2157185-A (GB)
Title: Mixing systems
Inventor: WEETMAN RONALD J
IPC: C02F3/16
Filed: 1985-02-21
Abstract: In the mixing of liquids having fibers suspended therein which tend to adhere to and accumulate on the leading edge of the impeller, the leading edge 38 of the blades 32 of the impeller 30 are inclined with respect to radial lines extending from the axis of rotation of the impeller beyond the angle of repose of the fibers on the leading edge. Also, the coefficient of friction of the portion of the impeller extending from the leading edge toward the trailing edge thereof, to which the fibers adhere is reduced by providing an insert 50 of a low coefficient of friction material. These two conditions contribute to the prevention of build-up of the fibres on the impeller & hence to the reduction of drag& the consequence increase in power for rotation of the impeller <IMAGE>
Patent GB-2173977-A (GB)
Title: Local area network
Inventor: ALLEN TIMOTHY RICHARD
IPC: G06F15/173
Filed: 1985-04-20
Abstract: In a local area network for use in high system integrity circumstances, e.g. for ship-board use, there is a number of nodes 1,2,...16 each serving a number of subscribers' lines, and each connected via respective links to a number, three in the present case, of other nodes. When the system is to be used, one node, e.g. the lowest- numbered node, is selected to be the master node. The system then configures itself under software control as a mesh in which every other node is connected to the master node, in each case using the minimum number of links. This system is a damage-tolerent, and any node can in fact function as a master node. If nodes or links fail the system reconfigures to take account of the failures, and in extreme cases of damage may reconfigure itself into two or more "sub-systems" each with its own master node. In the system shown there are two separate loops, nodes 1,6,4,8,2,15 and nodes,7,9,10,11,14,3,5,16,12, 13 with interloop links and a couple of bypass links on the larger loops. <IMAGE>

Title: A rack and pinion gear assembly
Inventor: ADAMS FREDERICK JOHN
IPC: F16H19/04
Filed: 1986-03-19
Abstract: A rack and pinion gear assembly suitable for steering systems has its rack bar 10 provided with convergent planar bearing surfaces 12, 13. The bar 10 is displaceable through a channel 14 in pinion housing 1 with the bearing surface 12 sliding over side wall 15 of the channel. Located between the bearing surface 13 and side wall 16 of the channel 14 is a wedge 18 which is biased by a spring 24 between the surfaces 13 and 16 to urge the rack bar 10 for its teeth 11 to engage the pinion 6. The wedge 18 may be irreversible so that it is not displaced against its biasing spring 24 in response to pressure applied on the wedge from forces generated between the rack and pinion in a sense to separate the teeth thereof. If the wedge 18 is reversible a stop (not shown) may be provided in the housing 1 to restrict the displacement permissible for the wedge against its spring 24. For non-triangular sectioned rack bars 10, adaptors can be provided to form planar bearing surfaces (corresponding to the surfaces 12 and 13) on a member carrying the rack teeth 11. <IMAGE>

Filed: 1986-06-11
Abstract: A high torque universal joint has a cross (10) formed by two mutually perpendicular pairs of coaxial trunnions (11), each pair of trunnions being rotatably received in bearings (26) which in turn are coaxially retained in blind bores (24) in the bearing caps (22) of one of two yokes (12, 12 min ). The yokes are subdivided into mating half sections (12a, 12b) which each include one of the bearing caps. The mating half sections are separably interconnected (48, 50) and are provided with juxtaposed confronting surfaces (38) lying on opposite sides of first yoke reference planes extending through the universal joint center (X). The mating half sections have end surfaces (52) which are adapted to abut the flanged ends (18) of rotatable elements (20) at second yoke reference planes. The first and second reference planes of each yoke are mutually perpendicular, and first and second key members (44, 54) are located respectively at the first and second reference planes. The restraining forces acting at the first and second yoke reference planes coact during service of the joint to prevent relative movement between the mating yoke half sections.
